Shaykh ul-Islām ibn Taymiyyah [may Allāh have mercy on him] said:
*“The greatest pleasure in this worldly-life is knowledge of Allāh and the greatest pleasure of the Afterlife is looking upon Him [He, Allāh is free from imperfection].”*
Majmū’ al-Fatāwa, 14/163 | Shaykh ul-Islām ibn Taymiyyah [may Allāh have mercy on him]
Greatest Blessing and achievement in this world is knowledge.
Greatest Blessing and achievement in Akhirah is Looking and Seeing Allah
